I’m focusing this talk on the idea that tagging might help designers organize huge amounts of information by letting their users do it for them. Heresy! You say. Well, in some places it might turn out that tagging beats IA hands down. In others, a traditional IA still works best.

However, if you’ve read The Del.icio.us Lesson, you know that it isn’t as simple as it seems at first glance. So I’ll be talking about the ins and outs of tagging, where it seems to work well, and where it doesn’t work.
